Web Services bring with them great possibilities and with these possibilities are some pitfalls. One such pitfall is passing complex data types to and from Web Services without losing data integrity. The clearest thing to keep in mind when passing objects to Web Services is the data is passed for your object\'s fields, but the code is not.

The Java API for XML-based remote procedure calls (JAX-RPC) simplifies the process of building Web services that incorporate XML-based RPC. It defines mappings between XML types and Java types that attempt to hide the details of XML and provide a familiar method-call paradigm. This introduction shows how developers can use JAX-RPC to implement and call SOAP-based Web services described by the Web Services Description Language (WSDL). Let\'s see how it works.

This second article discusses MSXML in detail. I use MSXML DOM to perform a WSDL to HTML transformation in order to generate a user interface for a web service. I will demonstrate the use of MSXML on both client and server sides. On the client side, I\'ll use JavaScript inside a browser and, on the server side, MSXML inside an ASP.NET page.

Many data formats are being used in the enterprise world that make it difficult for businesses to collaborate with one another at the application level. Web services enable interoperability through a set of XML-based open standards. Businesses can describe their Web services on the Internet using an XML-based language, such as the Web Services Description Language (WSDL), or simple plain text, and list them in an XML-based registry such as Universal Description, Discovery, and Integration (UDDI), or the electronic business XML (or ebXML) Registry. But since the formats of these XML-based registries are different, developers must study each of them carefully and in detail.

Have you ever wanted to roll your own Napster? J.P. Morgenthal, CTO of Akimbo, a real-time communications software provider, explained the basics of doing so in his class covering the use of the Simple Object Access Protocol (SOAP) and Web Services Definition Language (WSDL) to expose and invoke methods on remote machines. Unfortunately, Morgenthal was not able to fully execute the examples he had planned to show, because his machine was misconfigured.

This article discusses:Authentication techniques for .NET Web services Security and policy in WSE 2.0 The use of firewalls in protecting Web services ISA Server 2004 and WSDL . There are aspects of software design and development many of us would like to overlook because they\'re just not fun. The work we do in security, performance tuning, and optimization may not be glamorous, but it is essential. And while security has always been important, it is especially critical to today\'s Web applications because of the great financial risk that is posed by insecure code.

Your team has just built and deployed a Web service and you\'re waiting to see how it will be received. Will anyone find it? Will anyone use it? Will anyone like it? There\'s nothing more demoralizing that seeing the \"build it and they will come\" mantra fail after you\'ve invested so much time in building something.That\'s why it\'s important to note that although good technical execution is necessary for any piece of software\'s success, a Web service\'s success can be undermined by the lack of strategy and planning around the service itself.

When you listen to someone explaining Web Services, it\'s not unusual to hear WSDL compared to the Interface Definition Languages (IDLs) used by classic RPC mechanisms like DCE, ONC, CORBA, and COM. All of these technologies use IDL of one form or another to define contracts between components. In all of these cases, use of an IDL was the key to interoperability across language, process, and vendor boundaries. WSDL is exactly like the IDLs of the past in that a WSDL document describes the portTypes or interfaces a web service implements.

Emerging Technology Briefs, developed by O\'Reilly Research, offer a single-page summary of recent developments in a technology topic that we have been following. O\'Reilly Research also publishes full-length industry reports, including \"Planning for Web Services: Obstacles and Opportunities\" by Clay Shirky, from which some of the material for this brief was drawn. The report\'s Executive Summary is available online.

Unlike today\'s Web, web services can be viewed as a set of programs interacting cross a network with no explicit human interaction involved during the transaction. In order for programs to exchange data, it\'s necessary to define strictly the communications protocol, the data transfer syntax, and the location of the endpoint. For building large, complex systems, such service definitions must be done in a rigorous manner: ideally, a machine-readable language with well-defined semantics, as opposed to parochial and imprecise natural languages.
